Abstract (en)

[origin: EP0303244A2] Disclosed is a process for the preparation of rubber laminates, according to which a rubber laminate having a high bonding strength can be obtained by contacting an uncured composition A comprising a fluororubber and a metal oxide with an uncured composition B comprising an epichlorohydrin rubber and a phosphonium salt represented by the following general formula: <CHEM> wherein R1, R2, R3 and R4 each stand for a hydrocarbon residue having 1 to 20 carbon atoms, which may be substituted, with the proviso that up to three of R1, R2, R3 and R4 may be a primary, secondary or tertiary amino group or a fluoroalkyl group, and R5 stands for a hydrogen atom or an alkyl group having 1 to 20 carbon atoms, and curing the uncured compositions.
